a '70 Super Bee with an A30 "Scheduled Production Date" would've been scheduled 10/30/69

with a 8*5*69 casting date on the 440, it was probably installed in a 1970 model year car (F - series) when new.

what's the partial VIN on the 440? do you have a pic of the top pad from the 440?

the transmission is from a '70 Challenger built in Hamtramck, MI - is it 23 or 18-spline?
